初中现在完成时态讲解及练习(可编辑修改word版)

初三语法专项训练：现在完成时用法小结

现在完成时的构成：助动词have（has）+ 过去分词，

1．表示过去发生或完成的某一动作对现在造成的影响或结果。例如：

I have just cleaned my clothes. 我刚洗过衣服。

（“洗衣服”是发生在过去的动作，对现在造成的结果是“衣服干净了”）

现在完成时常用的时间状语有：already （”已经”用于肯定句的中间和末尾处）never (“从不”用于中间处)

ever （”曾经”用于疑问句和肯定句的中间处）

just (“刚刚”用于中间处)

yet (“已经”用于疑问句的末尾处/ “还”用于否定句的末尾处)

现在完成时与一般过去时的用法比较

现在完成时表示过去的动作一直延续到现在甚至会继续下去或表示过去的动作对

现在造成的影响；一般过去时表示动作发生的时间在过去。试比较：

The plane has arrived . 飞机已经来了。（说明现在的情况：飞机在这儿）

The plane arrived a quarter ago. 飞机是一刻中以前来的。（强调动作发生的时间在过去）

I have taught here for fifteen years. 我在这儿已经教了十五年。（表示十五年前的动作一直延续到现在，还可能会继续。）

I taught here for a year. 我过去在这儿教过一年。（表示“我“现在已经不在这儿任

教了）

Since 和for 的用法

表示过去已经开始持续到现在的动作或状态常用的时间状语有：for, since, how long, so far, these days 等。

Since+过去点的时间，for+一段时间（数词+量词），此划线部分用how long 提问。一、since 短语或从句表示过去的动作延续至今，since 之后的时间为一点。如：Mr. Smith has worked here since 1984. 1984 年以来，史密斯先生一直在这工作。He’s learned about 5,000 English words since he went to college. 他上大学以来大约学了

五千个英语单词。

二、for 短语表示动作延续多长时间，for 的宾语为时间段。如：
